The firft {kin, as in French-beans, may be eafily fepa- 
rated from the parenchyma, efpecially if the bean be 
foaked in water for fome days, it will flip eafily off, and 
will be found to confift of bladders, fmalier than thofe of 
the parenchyma, and intermixed with a kind of lignous 
fibres which give a toughnefs to the fkin. The branched 
veffels run through the parenchyma, and compofe the 
feminal root in the lobes, being no where extended to 
the circumference of the lobes, but are all inofculated 
together at a confiderable diftance from it ; all meeting 
therein in one folid nerve, but in the {talk are dilated into 
an hollow trunk, filled with a pith compofed of bladders, 
which in the {talks of French beans is very confpicuous ; 
they confift of fap and air veffels as the other parts of a 
plant, not running collateral, the latter being fneathed 
in the former, and are plainly vifible in the microfcope. 
Of the generation of the feed. 
A S a garden bean was chofe to fhew the manner of the 
feeds vegetation, fo an apricock is very fit to ob- 
ferve and reprefent the method nature takes in its gene- 
ration. 
A proper uterus’ is firft prepared, both to keep the 
membranes of the foetus warm and fucculent, and to 
preferve and fecure it afterwards till it takes root in the 
ground. For this purpofe both the pulp and ftone of the 
fruit are necefiaryj but firft the ftone, the pulp being 
only neceffary to form the ftone, the petrifying of that 
parenchyma which is the ground of the ftone, being 
effected by the finking of the tartar x thereinto j for
